Automatic gas column temperature controller. Temperature controllers

Every gardener or gardener dreams of having a greenhouse on his plot. A greenhouse is a kind of resort area where plants feel good regardless of weather conditions. And how pleasant and useful it is to get a crop of lettuce, radish in early spring when an ordinary liverwort appears on the newly appeared thawed patches!

Naturally, in order to obtain such results, it is necessary not only to construct good greenhouse but also to support there optimal temperature. Air and soil temperature is important.

These factors affect absorbency useful elements, moisture; qualitative and quantitative indicators of the harvest; occurrence of various diseases.

Any gardener should understand that there is a direct relationship between the temperature of the air, the soil inside the greenhouse, and the possible harvest. However, many neighboring cultures like different modes of humidity and temperature. By optimizing the placement of crops in the greenhouse, you can take advantage of the significant temperature difference in its various parts.

In the greenhouse, as well as in the unprotected ground, there are daily temperature fluctuations. Too sharp, exceeding 4 - 8 ° C, drops negatively affect the growth, development of plants, productivity. Lead to frequent diseases and death of crops. Depending on the type of plant, the temperature of the soil and air in the greenhouse should be at around 14 - 25 ° C.

To maintain the required temperature level in heating systems, electrical devices called thermostats are used. All devices with electric heating elements are equipped with electric thermostats.

The need and features of thermostats

The thermostat is electrical device necessary for automatic temperature control in the cooling and heating equipment. They are mounted in heating systems, artificial climate, cooling or freezing systems. Widely used in household in the arrangement of greenhouses.

The purpose of the thermostat is determined by turning on or off heating elements any appliance at temperatures below or above those specified, respectively. Due to the operation of thermostatic devices, indoor air, water, instrument surfaces, etc. I have a stable temperature.

All thermostats work, no matter what device they are in, according to a single principle. The automatic regulator receives temperature data from its environment, due to the fact that it is equipped with a built-in or remote temperature sensor. Based on the information received, the thermostat determines when to turn on and off. To avoid malfunctions of the device, the temperature sensor should be installed indoors away from the direct influence of various heating equipment, otherwise, distortion of the indicators may occur and, of course, the controller will work erroneously.

Classification of thermostats

The principle of operation of all devices that regulate the temperature is the same, but there are a lot of types of thermostats, and they differ in:

• Purpose:
  room;
  weather.
• Mounting method:
  wall;
  wall;
  mounted on a DIN rail.
• Functionality:
  central regulation;
  wireless regulation.
• Control way:
  mechanical;
  electromechanical;
  digital (electronic).

Also, thermostats differ in technical properties:

• Temperature measurement range. different models thermostats, depending on the modification, maintain a temperature from -60 to 1200 ° C.
• Number of channels:
  single-channel. Apply to automatic adjustment and maintaining the temperature of the object at the specified level. Differ in the smaller sizes and weight from multichannel devices;
  multichannel. Are issued for fixing of temperature of a series of standard thermal sensors. They are used in factories, laboratories, as well as in the national economy.
• Dimensions:
  compact;
  large;
  large.

Application of temperature controllers and sensors

Temperature controllers can be installed in residential and industrial premises. In general, the following can be distinguished:

• And controlling the air temperature in a specific area of ​​the room. These devices belong to the category of room regulators. There are analog and digital.
• And those that maintain the temperature of certain objects are regulators for underfloor heating.
• Outside air temperature - weather thermostats.

Regulators that are operated in industrial premises are of two types:

• Industrial spatial . These devices include analog wall regulators with increased protection.
• Industrial with separate sensors . These are analog devices with external sensors that can be wall-mounted or mounted on a special rail.
  Sensors can be installed on the walls or in the floor of the house, depending on their type and purpose. Built-in devices are mounted in a mounting box directly into the wall, while surface-mounted devices are simply attached to the wall.

There are also several types of sensors for their intended purpose:

• Floor temperature sensor.
• Air temperature sensor.
• Infrared sensor for floor and air.

A sensor that measures air temperature is often placed on the thermostat housing. Thermostats with infrared sensors can be used to control the entire heating system. These sensors are great for installation in bathrooms, showers, saunas and other environments with high humidity. The temperature controller itself must be placed in a dry place, it can be damaged from an excess of moisture. True, there are models with increased tightness, and their installation in the bathroom is not dangerous for them.

Regulators for underfloor heating differ in their internal structure, these are:

• Digital.
• Analog.

Digital devices have good resistance to different types interference, therefore eliminating data distortion and guaranteeing greater accuracy than analog.

Features of the functionality of electric temperature controllers:

• Wireless regulation (remote) . It is recommended to use for additional installation of heating elements and reconstructions, when it is impossible or rather difficult to perform classical adjustment. Remote control excludes additional construction and repair work during electrical installation (for example, installation of cable wiring).
• Programming devices . The central (classic) device allows you to control the temperature of an entire large object from one point. The controller is programmed using a computer or control devices. Also, control is carried out using a telephone modem.

Principle of operation, pros and cons

Mechanical temperature controller considered a simple and practical device. Used for heating and cooling purposes. Most often represents external wiring product designed for indoor installation in residential premises in heating systems. Appearance similar to a standard stopcock.

Specificity mechanical thermostats is the absence of an electrical component. The device works according to a special principle, which consists in the properties of certain substances and materials to change their mechanical properties from temperature changes.

When the temperature changes to a specifically specified one, a break or short circuit occurs electrical circuit, which causes the heating devices to be turned off or on. The required temperature indicator is selected on the instrument scale by rotating a special wheel.

Positive points of mechanical thermostats:

• Reliability.
• Resistant to voltage drops.
• Not subject to electronic failures.
• Work at negative temperatures.
• Can be used in conditions of sudden temperature changes.
• Simple control.
• Long service life.

Flaws:

• The presence of an error.
• The likelihood of small clicks when voltage is applied to infrared heaters.
• Low functionality.

Regardless of the shortcomings, they are the most common and are found in the organization of heating systems more often than other thermostats, due to simple control and low cost.

Operation of electromechanical thermostats

Electromechanical temperature controllers are used in various household electrical appliances. These products come in two versions:

• With bimetallic plate and group of contacts . The plate, heated to a certain temperature, bends and opens the contacts, due to which the supply of electric current to the heating coil or the heating element of the device stops. After cooling, the plate bends back to its original position, the contacts close, the electricity supply returns and the device heats up. Devices with these regulators are used in Everyday life almost every person is irons, electric stoves, electric kettles, etc.
• With capillary tube. The product consists of a tube filled with gas and placed in a container with water, as well as contacts. The principle of operation is based on the properties of materials to expand at certain temperatures. The substance in the hollow tube begins to expand when the water is heated, which causes the contact to close. After the water cools, the contacts open, and the appliance begins to warm up. Such regulators are most often equipped with water heaters, oil heaters, boilers.

• Automatic inclusion of heating.
• Tightness.
• Not high price.

Cons of these devices:

• Low functionality.
• Difficulty in achieving high control accuracy.

The specifics of electronic temperature controllers

Electronic devices are very common, they are operated with many electric heaters. Usually they are equipped with general heating and air conditioning systems, as well as underfloor heating.

Main components:

• Removable temperature sensor.
• The controller is a device that sets a specific temperature level in the house, as well as creating commands to turn the heater on and off.
• Electronic key - contact group.

The instrument's sensor sends temperature data to the controller, which processes the received signal and decides whether to lower or increase the temperature.

Types of electronic thermostats:

• Conventional thermostats . In these devices, you can set the desired temperature limits or the exact temperature that will be stored. The devices are equipped with an electronic display.
• Digital thermostats:
  Closed logic. Devices have an unchanged algorithm of operation. Regulation is carried out by sending commands for the specified parameters to specific devices that were installed in advance. The parameters are set in advance depending on the needs of the devices used for a certain temperature. Correction of the program of these controllers is practically impossible, you can only change the main parameters. But it is these thermostats that are most often used in everyday life.
  With open logic. These devices control the precise process of space heating. They have advanced settings, so you can change their algorithm of work. Controlled by buttons or touch panel. By means of these devices, it is possible to turn on or turn off heating systems at a strictly specified time. But their reprogramming should be handled by specialists. These regulators are used more often in production and industry than in everyday life.

Programmable thermostats are convenient to operate, they open up ample opportunities for fine-tuning devices to the desired temperature indicators, depending on the requirements of individual areas of the premises.

Advantages:

• Wide range of adjustments.
• Variety of design solutions.
• Saving electricity.
• High accuracy.
• Efficiency.
• Operational safety.

Also, thermostats are easy to manage and have no high cost, only these two pluses do not apply to open logic regulators. Electronic controllers are often integral part smart home systems.

In the article we will find out what thermostats can be for home heating. We will analyze the basic principles of work different devices of this type and tell you how to install them correctly. Let's start, however, with a few general concepts.

Why is it needed

But in fact, why do you need a thermostat for heating? Our grandparents did just fine without it and did not suffer at all ...

Saving

Do you remember what the rent was like in the days of grandparents? At the end of the seventies, in two-room apartment on the Far East where the author grew up, it was about 15 rubles. In winter, together with heating and electricity.

For comparison: the salary of a junior researcher at a local institute at that time was about 120 rubles. The average salary in the city, thanks to the northern and regional coefficients, is more than two hundred. It never occurred to anyone to worry about two or three rubles, which were overpaid for excess heat: it was easier to open the window.

However: even at the project level, all radiators were supplied with the great-grandfather of the current thermostats - three-way valve. It made it possible to reduce the flow of coolant through the radiator by completely or partially directing the flow of water into the jumper.

Now most of the state initiatives come down to two main theses:

1. Citizens don't need it.
2. And they have to pay for it themselves.

There are no more subsidies for the maintenance of housing, housing and communal services are in decline, rents are growing, but we ... are adapting as best we can.

Thermostats for heating radiators in conjunction with heat meters are one of the ways to reduce the cost of heating a home. Heat is consumed exactly as much as is necessary to maintain comfortable temperature at home. Not more.

Convenience

Yes, thermostats aren't the only way to save heat. Heating radiators can also be adjusted manually - with a throttle or a conventional valve.

But, as usual, there are nuances:

• The throttle regulates the patency of the eyeliner. With fluctuations in the temperature of the coolant, the heat transfer of the heater will also change.
• The need for heat varies depending on the temperature outside. Adjusting the patency of the throttle or valve manually several times a day is somewhat tedious.

An alternative to the throttle - the thermostat - is a fully automatic and weather-compensated heating controller. If the room becomes hot due to the increased temperature of the water in the battery, it will reduce the flow of water through it.

If it's cold, it will open up. And all this will happen without your participation.

Principle of operation

There are an infinite number of specific implementations of heating controllers. It is based on only two basic principles of regulation.

Mechanical regulator

Let's see how the Danfoss RAW-K 5030 thermostatic head works.

• The mechanism is based on a container with a liquid or gas with a high coefficient thermal expansion. The container tends to press the valve, blocking the flow of water; it is opposed by a conventional spring.
• Rough adjustment is carried out by the simplest screw mechanism. The closer the initial position of the temperature-sensitive element to the valve, the less stroke it needs to block the flow of water.
• In addition, many thermostats for heating radiators include an additional tuning mechanism - a simple choke. It helps to calibrate the thermostat so that the scale of conventional values ​​​​on it corresponds to real temperatures in the range from 7 to 28 degrees.

However: Fine adjustment can also be made with an ordinary throttle mounted on a second, thermostat-free connection to the heater.

The same principle applies, by the way, automatic regulator thrust for solid fuel boilers. The problem of inconsistency in the stroke of the damper and changing the size of the temperature-sensitive container is solved extremely simply - using a lever with arms of different lengths.

Electric regulator

All electric heating thermostats use the ability of certain materials to change their characteristics with temperature changes.

Of course, in this case we are talking about electrical characteristics:

• The thermistor changes its resistance as the temperature changes. Accordingly, at a constant voltage, more or less current will flow through it. So, for example, the heater fan speed controller often works. With a small power input, all the current can flow directly through the thermistor.

More complex scheme, however, will allow you to control large currents. So it works room regulator heating VRT 40 from Vaillant: with a current through a thermistor in fractions of an ampere, it can control an electric boiler with a power of tens of kilowatts.

• The thermocouple is an even more curious device. If you solder together two plates of different metals - for example, from nichrome and aluminum-nickel alloy - a potential difference will occur at the junction. Moreover, it will dynamically change with fluctuations in the temperature of the soldering point.

The resulting current will be in millivolts, and by itself is not enough to drive any valve; however, there are transistors for that. The control signal can be arbitrarily small and still control large currents.

The cascade of transistors will theoretically allow an ordinary thermocouple to control the supply of heat not only to a radiator, but even to an entire apartment building.

At general principle operation of electrical thermostats can be analog or digital. The first allow only the simplest setting temperature and are most often equipped with a simple indicator, combined with control - a wheel with a scale. The latter can not only set the current temperature, but also be programmed for a day or a week.

In addition, digital indicators are further divided into two categories:

• Devices with closed logic only allow setting the basic parameters within the factory firmware. They are relatively easy to set up, but have manufacturer-limited capabilities. A typical example is the Calormatic 430 automatic heating controller from Vaillant.

• Open logic devices can be completely reprogrammed. Instead of so-called one-shots - non-erasable chips with firmware - they are equipped with conventional flash memory with an open interface.

These devices are rarely used in heating systems of private houses: the complexity of setting up and the high price scare away buyers. But the possibilities that an open logic heating thermostat has are impressive.

Here is a list of functions of the Ukrainian heating regulator Rise RO-2:

• Temperature control taking into account the thermal inertia of the building.
• Calculation temperature chart compensating for sudden temperature fluctuations outside.
• Protection of the heating network from overloads by rationing the flow hot water.
• Building a temperature graph for administrative buildings according to their mode of operation.
• Calculation of the heat carrier flow in accordance with the current contract with the heat supplier.

It's easier to say what this thermostat can't do. In addition, if required additional functions- it can be reflashed.

Installation rules

thermostatic heads

If heating radiators with a thermostat are supplied ready for connection, then the thermostat purchased separately must still be mounted.

How to do it yourself right?

• The installation method itself is no different from the assembly of other threaded connections. Be aware of the brittleness of the brass body: when assembling threaded connections, avoid using too much force. The best thread take-up that is easy to find in any store is sanitary flax; to make it more durable - soak a strand of linen with any paint.
• The thermostat for heating radiators is always located on the supply line. On the reverse thread will great idea insert a valve that allows you to completely cut off the heater. If a throttle for manual calibration is not built into the thermostatic head, the valve can be replaced with a separate throttle.

Attention: the presence of a jumper when installing ANY throttle or thermostat is mandatory. Without it, you will regulate the patency of the riser or the entire heating circuit of a private house.

• When two-pipe system heating, the use of chokes is mandatory. They are needed to balance the circuit: the batteries closest to the boiler or elevator will have to be pressed, reducing the coolant flow through them. Otherwise, distant radiators simply will not heat up - up to defrosting in extreme cold.

Balancing is carried out with the thermostatic heads fully open (maximum temperature value on the dial). Only after all the heaters start to heat up to approximately the same temperature, you can adjust and calibrate the thermostats.

• If you are installing a heating system in a one-story private house, the best choice Leningradka will become - a single-pipe circuit along the perimeter of the house, parallel to which, without opening it, heating appliances crash.

Connection diagram - bottom or diagonal. A throttle is placed on one of the connections (balancing is not necessary here, but desirable). The second is the thermostat.

• The head is usually placed horizontally. What is the instructions for? The point is that at vertical installation the heat sensing element will often be caught in the hot air rising from the radiator. It is clear that its temperature will have little to do with the AVERAGE temperature in the room.

Electronic regulators

Installation rules depend on where the controller temperature sensor is located.

If it is built into the control panel, it must be mounted according to quite understandable restrictions:

• Height above floor level - not less than 80 centimeters. Close to the floor, the temperature is noticeably lower. Especially with an open window or door to the hallway.
• Out of the updrafts of any heating appliances and generally heated structures. Heat from the back of a refrigerator will affect sensor calibration just as much as a radiator.
• Direct sunlight will also affect the operation of the device. Place the panel with the sensor in the shade.
• Finally, it would be unwise to place the electronic control panel where the wall is often touched by the inhabitants of the house passing nearby.

If the thermostat uses a remote sensor, all items except the last one will refer specifically to the location of the sensor. The panel is mounted where it is convenient for you.

Conclusion

In the video at the end of the article, you can take a closer look at some types of thermostats and the rules for their installation. Different manufacturers may have quite different installation requirements, so be sure to read the instructions.

As you know, in order to heat any room with high quality, it is necessary to correctly adjust the temperature indicators so that the heating matches optimally. comfortable conditions and provided a favorable microclimate in the dwelling. Therefore, it is necessary to consider in more detail the features of such a device as a temperature controller for a heating radiator, which is designed to perform all these functions. In addition, you should figure out how to regulate the temperature of the radiator in various buildings, including private and apartment buildings.

The need to install thermostats

Such mechanisms are used for the following purposes:

• saving heat produced by heating;
• maintaining a comfortable temperature in the home.

Many owners to solve the second problem still use traditional ways such as covering radiators with a blanket or opening windows for ventilation. However, much more modern solution there will be the installation of such a device as a heating temperature controller, which affects the flow rate of the coolant in the heating system and is capable of functioning both in manual and automatic mode.

It is very important to remember that during installation it is extremely necessary to have a special jumper located directly in front of the heating device. If it does not exist, then the coolant flow cannot be regulated through the radiator, since this will have to be done through a common riser.

Speaking of savings, this factor is relevant for those owners whose living quarters are equipped with an autonomous heating system, as well as for housing and communal services that use metering devices to pay for heat coming from its producers.

Installation of temperature controllers in apartment buildings

To set the radiator temperature controller to apartment building, it is necessary to understand what constitutes heat accounting in such a design.

The supply and return pipelines are equipped with special retaining washers, before and after each of which there are pressure regulating sensors. Due to the fact that the diameter of these sensors is known, it becomes possible to calculate the flow rate of the coolant circulating through the sensors. As a result, the difference obtained between the water flow in the supply and return pipelines will reflect the amount of water used by the residents.

Temperature sensors are designed to control both areas. Therefore, knowing how much heat is consumed and what its temperature is, you can easily calculate the amount of heat that remains in the room.

In order to regulate the operation of heating was easier, you need to constantly monitor the state of the temperature.

This can be done in one of two ways:

1. Mounting shut-off valve . Such a device is designed to partially shut off the pipeline system if the return temperature is higher than the set one. Represents an ordinary solenoid valve. This option will be suitable for those houses where the heating system is relatively simple and does not have a large volume of coolant.
2. Valve device three way type . This device also allows you to adjust the current flow rate of the coolant, but it functions a little differently: in the event that the water temperature exceeds the norm, then it is sent through open valve into the supply pipeline more. By mixing with cooled water, the overall temperature will decrease, while the required circulation rate will be maintained.

Similar design may differ slightly in different systems. The device circuit can be equipped with several temperature sensors, as well as one or two circulation pumps. Also, valves may be present. mechanical type, with which you can control the operation of heating without supplying any power.

Installation of mechanical regulators is not particularly difficult. To install such a device, you only need to connect it to the flange in the elevator assembly. It is also important that the price of such devices is much lower compared to electronic mechanisms.

Installation of temperature controllers in private homes

As a rule, an automatic heating temperature controller is an integral part of a heating boiler in autonomous system heating. Such a sensor can be mobile, that is, it can be carried, and is also capable of measuring the temperature in the room.

Electric boilers use electronic sensors, which are directly connected with the installed heating elements (thermal electric heating elements) or with the voltage that occurs on the electrodes or on the boiler winding.

Boiler systems operating both with gas and pyrolysis technology are often equipped with mechanical regulators, the main advantage of which is independence in terms of energy. But this option, of course, does not imply the use of remote temperature sensors. See also: "".

Temperature sensors for radiators

Sometimes one temperature sensor carries several heating radiators. First of all, the installation scheme affects this. But it is much more common to mount the regulator on each heating device separately.

Many owners install a system familiar to many, called "Leningrad", the principle of which is to use one pipe encircling a house or one floor, which has a rather impressive diameter, and radiators or convectors are built in parallel with it.

It is worth noting that in order to adjust the heating temperature, you can use not only standard devices.

Common mechanisms of this type include:

• thermostatic head. Represents automatic sensor, which controls the temperature of the coolant in the battery. The principle of its operation is as follows: in the process of heating, liquid and gaseous substances expand (details: ""). This, as a consequence, leads to the fact that the heated product squeezes out a special rod, thereby blocking the access of the coolant;
• devices called chokes are no less often used. They are special taps. screw type, with which you can adjust the permeability of the coolant manually. Their cost is more affordable, and in addition, they can be used to control two-pipe heating systems;
• The least expensive and simplest mechanism to help regulate temperature is the traditional valve. Of course, in this case, you should only use modern models, and not outdated screw devices, since valves are very often torn off in old mechanisms, and there is also a risk of oil seals leaking. The situation is completely different with ball valves: even in the half-open position, they function reliably and efficiently over a long period of time.

In order for the device of temperature controllers to be as convenient as possible, many experts recommend that you first study various photos these devices and detailed videos on their correct connection.

An example of heating temperature controllers on video:

Installing meters and believing that savings have been achieved is a delusion. Don't stop there! Having studied the market of energy-saving equipment properly, it comes to the understanding that real savings begin with the installation thermomiser. After all, this device should be used in every heating and hot water supply system! The thermostat is automatic temperature controller both hot water and coolant. By equipping your system with a thermomiser, you get the ability to control the climate in any room and huge savings in hot water or heat carrier consumption, and as a result, money.

How does a thermometer work?

The thermomiser consists of only two components, this is a regulator and electronic device management. The first component, the regulator, is responsible for automatically regulating the temperature of the supply water for the heating or hot water supply system. The second component of the thermomiser is an electronic device that receives data from temperature sensors located inside and outside the room, as well as at the inlet and outlet of the coolant. The received data is processed in accordance with the program algorithm, calculations are made, according to which commands are sent directly to the controller.

What can thermostats do?

By selecting various programs, we have the ability to maintain the set water and heat carrier temperatures, the schedule of the heating system, adjust the temperatures of the return circuit, the heat carrier in the supply pipe according to the deviation from the set internal temperature of the room, adjust when using a timer, separate modes for holidays, weekends and nights and a number of other options. Thermomisers are equipped with rich functionality and saving opportunities, we only need to select the right model, set the right data and set the mode.

An important detail in saving is the equipment of the device outdoor sensor, this is especially true for spring, during sharp changes in temperature at night and day. When monitoring the entire dynamics of differences, we always have the temperature we need inside the room without overspending resources and money.

Which thermostat to choose?

Thermizer should be chosen based on the existing water supply and heating system. Any thermomiser model will effectively save the coolant and create the necessary microclimate in the room. Depending on the type of regulator, some thermomisers can be used in systems of public and administrative buildings, others will be more relevant in open system hot water supply and heating, the third type of thermomisers is better applicable in closed systems with pump mixing, or as an additional option in ventilation systems and air conditioning systems. The most influencing factor in the savings of a thermomiser is the type of regulator.

Our factory manufactures and supplies all the lineup the following temperature controllers:
thermomiser R-2.T, thermomiser R-7.T, thermomiser R-8.T, Teplur control device and other components of ultra-efficient energy saving equipment. You can seek advice on the selection, purchase, delivery, installation and configuration of thermomisers using the contacts indicated on the product page.

How long do thermostats last and how are they used?

In terms of service life, thermomisers are practically eternal, but the quality of the coolant has a direct dependence on the lifetime of the device. Considering the realities, the thermomiser will work freely for 15-20 years. Our factory manufactures regulators from high-quality metals such as stainless steel, brass and cast iron, which has a positive effect on the durability and smooth operation of the devices. This gives significant advantages over imported devices - competitors made of carbon steel, manufactured by Danfoss, etc. The quality of the primary Russian coolant is significantly inferior to the European one, for which imported thermal misers are designed, their operation in domestic systems will be accompanied by many problems.

Thermomisers in maintenance are not whimsical at all. Basically, no Maintenance and not required. It is enough to set up the controller once initially. It is recommended to delegate installation to professionals.

Benefits of installing a thermostat

Often, when the coolant passes through the circuit heating system it does not cool down and has enough high temperature to use it again. This is exactly what is done with a thermometer. Due to the secondary use of the coolant, we achieve significant savings. Administrative, residential and public buildings can be connected in this way.

For the time when we do not use the premises, for example, on weekends or holidays, you can set minimum temperature coolant on the thermomiser, which will entail a significant reduction in coolant consumption.

Thermomisers also save money thermal energy in production and retail space. For this energy you have to pay a lot of money on the meter. Just imagine what kind of overpayment is received for weekends, holidays, night time and other cases when the premises are not used. For all these cases, you can set up certain modes in the thermomiser controller and not pay extra money for overspending the coolant.

The advantages of thermomisers are expressed not only in money, do not forget about comfort. After all, the ability to adjust and support on required level temperature is relevant for many rooms of various buildings and areas.
